Abstract
THE microtron which has been under construction at this College is now operating and accelerates electrons to an energy of 29 MeV., which is slightly greater than the design figure. The poles of the electromagnet are 80 in. in diameter and form the top and bottom of the vacuum chamber. The machine operates in the fundamental mode with a 2 MW. pulsed radio-frequency supply, of frequency 3,000 Mc./s. The current in the final orbit (57th) is about 10−9 amp. average and it should be possible to increase this considerably by fitting an emitting ring into one of the lips of the cavity. Due to the very close machining tolerances achieved by Edgar Alien and Co., Ltd., it was found that very little shimming of the magnet was required.
